如何通过运行 spring boot 测试代码来解决这个问题？

Question

这是我在 Spring Boot 中的测试代码。

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import com.myname.pjt.springboot.web.HelloController;

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = HelloController.class)
public class HelloControllerTest {

    @Autowired
    private MockMvc mvc;

    @Test
    public void hello_will_return() throws Exception {
        String hello = "hello";
        mvc.perform(get("/hello")).andExpect(status().isOk()).andExpect(content().string(hello));
    }
}

这是错误信息。

我不知道如何解决这个问题...

我试过这些。

1. 更改设置 > 构建、执行、部署 > 构建工具 > Gradle > 运行测试使用 > 将“Gradle（默认）”更改为“IntelliJ IDEA”

2. 在@WebMvcTest中添加secure = false

-> @WebMvcTest(controllers = HelloController.class) 到 @WebMvcTest(controllers = {HelloController.class}, secure = false)

但它仍然不起作用...... 请帮帮我...

这也是我的build.gradle。

buildscript {
    ext {
        springBootVersion = '2.1.7.RELEASE'
    }
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group 'com.myname.pjt'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

您似乎正在使用 JUnit 5 运行测试，但使用 JUnit 4 注释（org.junit.Test 与 org.junit.jupiter.api.Test）声明您的测试，这就是它没有在您的测试中起作用的原因。
